Two, build a new LRT system with significant design
enhancements. Mr Lee then noted the current system is more suitable
as an airport shuttle plying short distances on flat ground,
however currently BPLRT trains have to tackle gradients.

The third option was to renew the existing Bombardier
system with a more updated signalling system where trains could
tracked more accurately as they operated at higher frequencies.

If all three options are not feasible, there was
another alternative - to scrap the system and revert to buses. The
Government has ruled out this alternative, saying it would lead to
heavy congestion on the roads.

The first option has also been ruled out.

Asked for more details on the renewal process of the
BPLRT, the LTA would only say that it will be "a complex
project".

"We also need to minimise any inconvenience to
commuters as these works will have to be done on a live and running
system," said an LTA spokesman
